Metacarpophalangeal Joint Arthroplasty Based on the Osseointegration Concept

The osseointegration concept has been used for fixation of 68 MP joint endoprostheses in 31 patients operated on at the Department of Hand Surgery, Malmö General Hospital during the period 1988–1992. The indications were rheumatoid arthritis (50 joints), primary osteoarthrosis (three joints), post-traumatic osteoarthrosis (three joints), post-traumatic osteoarthrosis (five joints), post-infectious osteoarthrosis (seven joints) and joint deformities secondary to spastic conditions (three joints). The average follow-up time was 2.5 years (6–54 months). The surgical procedure included resection of the joint followed by introduction of screw-shaped titanium fixtures into the bone marrow cavities of the metacarpal and the phalangeal base. Rheumatoid cases usually required grafting of cancellous bone and marrow from the iliac crest. At the same time a flexible constrained silicone spacer was connected to the titanium fixtures in such a way as to allow later replacement of the spacer if accessory. The average active range of motion (ROM) was 57° in the rheumatoid cases and 50° in all cases. Radiological and clinical osseointegration occurred in every case, and there were no clinical signs of loosening. In four cases (6%) there was a fracture of the joint mechanism. Patient satisfaction was high, with pain relief, increased range of motion, improved hand function and good cosmetic appearance.

Hand injuries and cold sensitivity: Reliability and validity of cold sensitivity questionnaires

Purpose. Sensitivity to cold is a common consequence of hand injuries and other conditions, and this phenomenon has a profound effect on health-related quality of life and upper-extremity disability. The aim of the present study was to examine the reliability and validity of the Swedish version of the Cold Sensitivity Severity (CSS) scale and Cold Intolerance Symptom Severity (CISS) questionnaire and the reliability of the Potential Work Exposure Scale in a group of patients with traumatic hand-injury or vibration-induced problems. Method. We translated the self-administered questionnaires into Swedish and performed tests of reliability and validity. The questionnaire was sent to 159 patients with hand injuries. Results. Validity and internal-consistency results are based on a sample of 122. Test – retest results are based on a sample of 100. Good construct validity was demonstrated via correlation statistics. There were high correlations for both the CSS scale and CISS questionnaire scores with single questions concerning cold sensitivity, with the Disability of the Arm, Shoulder and Hand scale, and with the bodily-pain subscale of the SF-36 questionnaire. Reliability (both internal consistency and test – retest) was excellent. Conclusions. We conclude that the Swedish versions of the CSS scale and CISS questionnaire are reliable, and that this study provides evidence of the validity of the scales. The Potential Work Exposure Scale is reliable method of assessing exposure in the workplace.

Self-reported cold sensitivity in normal subjects and in patients with traumatic hand injuries or hand-arm vibration syndrome

BackgroundCold sensitivity is a common and disabling complaint following hand injuries. The main purpose of this study was to describe self-reported consequences of cold sensitivity and the association with disability and health-related quality of life in patients with hand injuries or hand-arm vibration syndrome (HAVS) and in normal subjects.MethodsResponses to the Cold Intolerance Symptom Severity (CISS) questionnaire, Potential Work Exposure Scale (PWES), Disability of the Arm, Shoulder and Hand (DASH) and Short-Form 36 questionnaire (SF-36) were investigated in normal subjects (n = 94), hand injured patients (amputation and nerve injuries, n = 88) and patients with HAVS (n = 30). The results are presented as median (range), percent and mean deviation from norms. The Kruskal Wallis Test or Mann-Whitney U-Test were used to identify significant differences between multiple groups or subgroups. The Spearman rank correlation was used to study the relationship between cold sensitivity and disability.ResultsAbnormal cold sensitivity (CISS score > 50) was seen in 75% and 45% of patients with HAVS and a traumatic hand injury, respectively. Patients were significantly more exposed to cold in their work environment than the normal population, with a consequently negative effect on work ability due to cold sensitivity. Patients with abnormal cold sensitivity were more seriously disabled and had a poorer health-related quality of life than patients with normal cold sensitivity [higher DASH scores and e.g. significantly larger mean deviation from norms in the subscales Role Physical and Bodily Pain (SF-36)].ConclusionSevere and abnormal cold sensitivity may have a profound impact on work capacity, leisure, disability and health-related quality of life. It is frequently seen in patients with traumatic hand injuries and particularly apparent in patients with HAVS.

Cut-Off Value for Self-Reported Abnormal Cold Sensitivity and Predictors for Abnormality and Severity in Hand Injuries

Our aim was to identify a cut-off value for self-reported, abnormal cold sensitivity and to identify cold sensitivity predictors after hand injuries. The Cold Intolerance Symptom Severity (CISS) questionnaire and a VAS question concerning discomfort on exposure to cold were investigated in 94 normal people and 88 patients. A CISS score>50 was defined as abnormal cold sensitivity. Multiple injured digits, an increased number of injured vessels, complete nerve injury and replantation were variables associated with high VAS scores. Factors linked to both abnormality and worse CISS or VAS scores were: the presence of bone injury; a larger number of repaired vessels; the use of vascular grafts and a high Hand Injury Severity Score (HISS). The causes of abnormality and severity suggest a multifactorial aetiology with bony, vascular and neural components. A cut-off for abnormality is useful for descriptive, comparative and assessment purposes.

Patients' views on early sensory relearning following nerve repair—a Q-methodology study

Study Design: Descriptive study. Introduction: Early sensory relearning where the dynamic capacity of the brain is used has been shown to improve sensory outcome after nerve repair. However, no previous studies have examined how patients experience early sensory relearning. Purpose of the Study: To describe patients views on early sensory relearning. Methods: Statements′ scores were analyzed by factor analysis. Results: Thirty‐seven consecutive adult patients with median and/or ulnar nerve repair who completed early sensory relearning were included. Three factors were identified, explaining 45% of the variance: (1) “Believe sensory relearning is meaningful, manage to get an illusion of touch and complete the sensory relearning”; (2) “Do not get an illusion of touch easily and need support in their sensory relearning” (3) “Are not motivated, manage to get an illusion of touch but do not complete sensory relearning”. Discussion: Many patients succeed in implementing their sensory relearning. However, a substantial part of the patient population need more support, have difficulties to create illusion of touch, and lack motivation to complete the sensory relearning. To enhance motivation and meaningfulness by relating the training clearly to everyday occupations and to the patient′s life situation is a suggested way to proceed. Conclusion: The three unique factors indicate motivation and sense of meaningfulness as key components which should be taken into consideration in developing programs for person‐centered early sensory relearning. Level of Evidence: 3.

The effect of early relearning on sensory recovery 4 to 9 years after nerve repair : a report of a randomized controlled study

Twenty patients randomized to early sensory relearning (nine patients) or traditional relearning (11 patients) were assessed regarding sensory recovery 4 to 9 years after median or ulnar nerve repair. Outcomes were assessed with the Rosen score, questionnaires, and self-reported single-item questions regarding function and activity. The patients with early sensory relearning had significantly better sensory recovery in the sensory domain of the Rosen score, specifically, discriminative touch or tactile gnosis and dexterity. They had significantly less self-reported problems in gripping, clumsiness, and fine motor skills. No differences were found in questionnaires between the two groups. We conclude that early sensory relearning improves long-term sensory recovery following nerve repair. Level of evidence: I

Congenital thumb anomalies and the consequences for daily life: patients’ long-term experience after corrective surgery. A qualitative study

Abstract Purpose: The aim of the study was to explore patients’ long-term experience of a congenital hand problem, and the consequences for daily life. Method: Fifteen participants with a median age 24 years (17–55 years), born with thumb hypoplasia/aplasia or thumb duplication were interviewed using a semi-structured interview guide. The interviews were subjected to qualitative content analysis. Results: Although the mobility and strength in the thumb/hand(s) varied within the group, hand function was generally described as good. Compensatory strategies were used to overcome practical obstacles. The emotional reactions to being visibly different from peers in early life varied from total acceptance and a sense of pride in being special, to deep distress and social withdrawal. Support from parents, teachers and others was important in facing emotional challenges and practical consequences. Conclusion: The present study highlights the importance of healthcare professionals addressing appearance-related concerns which may have long-term emotional and social consequences for patients born with a thumb anomaly. Implications for Rehabilitation Appearance-related concerns and need for emotional support should be fully considered throughout the rehabilitation process to prevent distress and social withdrawal. Effective problem-solving strategies, such as compensation, change in occupational performance and support from others may reduce activity limitations and participation restriction.

Atypical sensory processing pattern following median or ulnar nerve injury — a case-control study

BackgroundDue to brain plasticity a transection of a median or ulnar nerve results in profound changes in the somatosensory areas in the brain. The permanent sensory deprivation after a peripheral nerve injury might influence the interaction between all senses.The aim of the study was to investigate if a median and/or ulnar nerve injury gives rise to a changed sensory processing pattern. In addition we examined if age at injury, injured nerve or time since injury influence the sensory processing pattern.MethodsFifty patients (40 men and 10 women, median age 43) operated due to a median and/or ulnar nerve injury were included. The patients completed the Adolescent/Adult Sensory Profile questionnaire, which includes a comprehensive characterization on how sensory information is processed and how an individual responds to multiple sensory modalities. AASP categorizes the results into four possible Quadrants of behavioral profiles (Q1-low registration, Q2-sensory seeking, Q3-sensory sensitivity and Q4-sensory avoiding). The results were compared to 209 healthy age and gender matched controls. Anova Matched Design was used for evaluation of differences between the patient group and the control group. Atypical sensory processing behavior was determined in relation to the normative distribution of the control group.ResultsSignificant difference was seen in Q1, low registration. 40% in the patient group scored atypically in this Quadrant compared to 16% of the controls. No correlation between atypical sensory processing pattern and age or time since injury was seen.ConclusionA peripheral nerve injury entails altered sensory processing pattern with increased proportion of patients with low registration to sensory stimulus overall. Our results can guide us into more client centered rehabilitation strategies.

Hand Rehabilitation in Sweden: an Occupational Analysis with the Focus on Specialisation and Educational Objectives

The aim of the present study was to describe professional activities and analyse occupational therapists’ (OTs) and physiotherapists’ (PTs) practice. Members of the Swedish Society for Hand Rehabilitation participated (84 OTs and 26 PTs). A self-report questionnaire was used. It included questions of a demographic nature and questions concerning methods for assessment and intervention. The response rate was 85%. Professional activities specific to OTs and/or PTs were identified as well as core activities evaluated as very important. A large proportion of respondents supported a formal certification process, emphasising specific professional development, as well as joint specialised education organised at masters level where OTs and PTs shared professional knowledge. The data from this occupational analysis has served as a basis for educational objectives for PTs and OTs working in the field of hand rehabilitation.
